Abstract

Disclosed herein is a composition comprising cyclosporin A at a concentration between about 0.001% (w/v) and about 1.0% (w/v), a plant oil at a concentration between about 0.01% (w/v) and about 10% (w/v), and macrogol 15 hydroxystearate at a concentration between about 0.01% (w/v) and about 10% (w/v).

What is claimed is: 
     
         1 . A method of treating atopic or vernal keratoconjunctivitis, the method comprising administering to the eye of a mammal a composition comprising:
 cyclosporin A at a concentration between about 0.001% (w/v) and about 1.0% (w/v);   a plant oil at a concentration between about 0.01% (w/v) and about 10% (w/v);   macrogol 15 hydroxystearate at a concentration between about 0.01% (w/v) and about 10% (w/v); and   water.   
     
     
         2 . The method of  claim 1 , wherein the cyclosporin is present at a concentration of between about 0.01% and about 0.05% (w/v). 
     
     
         3 . The method of  claim 1 , wherein the macrogol 15 hydroxystearate is Solutol® HS 15 and is present at a concentration of between about 0.25% (w/v) and about 0.75% (w/v). 
     
     
         4 . The method of  claim 3 , wherein the plant oil is anise oil, castor oil, clove oil, cassia oil, cinnamon oil; almond oil, corn oil, arachis oil, cottonseed oil, safflower oil, maize oil, linseed oil, rapeseed oil, soybean oil, olive oil, caraway oil, rosemary oil, peanut oil, peppermint oil, sunflower oil, eucalyptus oil, sesame oil, coriander oil, lavender oil, citronella oil, juniper oil, lemon oil, orange oil, clary sage oil, nutmeg oil, tea tree oil, coconut oil, tallow oil, or lard. 
     
     
         5 . The method of  claim 4 , wherein the composition comprises castor oil at a concentration of between about 0.25% (w/v) and about 0.5%. 
     
     
         6 . The method of  claim 5 , further comprising a tonicity agent at a concentration between about 0.1% (w/v) and about 10% (w/v). 
     
     
         7 . The method of  claim 6 , wherein the tonicity agent is glycerin, sodium chloride, potassium chloride, or mannitol. 
     
     
         8 . The method of  claim 7 , wherein the tonicity agent is glycerin at a concentration of between about 1.0% (w/v) and about 1.5% (w/v). 
     
     
         9 . The method of  claim 8 , further comprising a buffer. 
     
     
         10 . The method of  claim 9 , wherein the buffer is an acetate buffer, a citrate buffer, a phosphate buffers, or a borate buffer. 
     
     
         11 . The method of  claim 10 , wherein the buffer is boric acid at a concentration of between about 0.6% (w/v) and about 0.7% (w/v). 
     
     
         12 . The method of  claim 11 , further comprising Polysorbate 80 at a concentration of between about 0.1% (w/v) and about 10% (w/v). 
     
     
         13 . The method of  claim 12 , wherein the Polysorbate 80 is present at a concentration of between about 0.25% and about 0.5% (w/v). 
     
     
         14 . The method of  claim 13 , further comprising POE-40 stearate at a concentration of between about 0.1% and about 10% (w/v). 
     
     
         15 . The method of  claim 14 , wherein the POE-40 stearate is present at a concentration of about 0.5% (w/v). 
     
     
         16 . The method of  claim 14 , further comprising Pemulen Tr-2 at a concentration of between about 0.01% (w/v) and about 10% (w/v). 
     
     
         17 . The method of  claim 16 , wherein the Pemulen Tr-2 is present at a concentration of between about 0.075% (w/v) and about 0.1% (w/v). 
     
     
         18 . The method of  claim 17 , further comprising hydroxypropyl methyl cellulose or carboxymethyl cellulose at a concentration of between about 0.01% (w/v) and about 10% (w/v). 
     
     
         19 . The method of  claim 18 , wherein the hydroxypropyl methyl cellulose or carboxymethyl cellulose is present at a concentration of between about 0.1% (w/v) and about 0.5% (w/v).
